SPECIFICATION forming part of Letters Patent No. 625,989, datedMay30,1899. I

Application filed September 16, 1898. Serial No. 691,102. (No model.)

To al whom, it may concern:

Be it known that I, JOHN AUTEs LATROBE SNYDER, a resident of Somis, inthe county of Ventura and State of California, have invented certain newand useful Improvements in Combination-Padlocks; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improvement in combination-locks, andparticularly to padlocks designed for use as bicycle-locks, such asshown and described by Letters` Patent granted to me on the th day ofMay, 1898, No. 603,7l1,the object of my presentinvention being tosimplify, improve, and strengthen the construction disclosed by myformer patent, whereby to simplify and improve the same and render itmore efficient, secure, and convenient to manipulate.

With these objects in' view my invention consists in certain novelfeatures of construction and combinations and arrangements of z5parts,as will be more fully hereinafter devs'ciibed, and pointed out inthe claims.

In thc accompanying drawings, Figure l is a view in perspective of myimproved lock. Fig. 2 is a longitudinalsectionai View. Figs. 3 and 4 arevertical transverse sectional views. Figs. 5 and 6 are horizontal trans-Fig. 7 is aview showing tumbler 16, a locking-plate 18, Aand a washer22. Fig. lS is a detail viewshowing one of the shackle-legs and therelation of the securing-pin 9 thereto. Fig. 9 is a longitudinalsectional View of the lock-casing with the tumblers removed and theshackleshown in elevation.

' l represents the body portion or casing of my improved lock and ispreferably composed of asin gie piece of metal provided with alongitudinal slot or opening 2 a little to one side of the centerthereof, intersected by a plurality of tumblers or pin-guides 3, fiveofthese guides or holes, arranged alternately, being shown in thedrawings.

The shackle 4 is provided with a long arm y 5 and a shorter arm, adaptedto be fitted in formed parallel with parallel shackle-arm yguides orsockets 7 8,

thelongitudinal slot or opening 2. A key or securing-pin 9 is disposedin a key guide or socket 10 in close proximity to the long shackle-armsocket 7 end. The key or pin 9 is provided at its upper end with a lugor projection 11, adapted to bear against a flat portion 12 of the longshackle-arm 5, said long shackle-arm having a shoulder 13 atthe upperend of the fiat portion and a shoulder 14 at the lower portion thereofand provided with a groove or recess l5 near its lower end, extendingpartially around it to permitthe partial turning of the shackle when thelock is unlocked and the pin or key 9 is in place. A

pin seats or guides 3 are the tumblers or lockthan the width of thelock-casing and fitted between the walls ofthe slot or opening 2, Withcoiled springs 17 and locking-plates 18. Each plate 18 is provided withan elongated slot 20, enlarged and rounded at one end, as at 21, so asto be of sufficient size to permit a tumbler or pin 16 to turn therein.Each tumbler or pin is provided with parallel dat faces 23, which areengaged by the contracted portion of the slot or opening 2O ofa plate 18when .the tumbler or locking-pin is in the p0- sition desired. Eachtumbler or locking-pin 16 is provided with two of these plates 18 (atthe respective walls of the opening or slot 2) and have the coiledspring 17 between them,

16 to be pushed in either direction and returned to their normalposition. Suitable washers 22 may be placed at each end of the spring toprevent its displacement when the plates are moved. The plates 18 whentheir slots 2O are fitted in portions 23 of the tumblers or pins 16 willmove therewith andprevent any unauthorized withdrawal of the tumblers orpins.

The shackle-legs 5 6 and the key or pin 9 are recessed or` cut away inthe planes of the tumblers or locking-pins to form tumblersimilarly cutaway or recessed at intervals on one side in alinement with theshackle-legs and key or pin 9 and are cut away or recessed on theirvopposite sides slightlyout of the and communicating therewith near itsupper Fitted in the transverse tumbler or locking- 1 thus permitting thetu mblers or locking-pinsy ing-pins 16, each being of a length greaterseats 25,- and the tumblers or locking-pins are IOO ' eating numeral orsign, and when it is desired to form a certain combination it is simplynecessar to give the tumbler or locking-pin a half-turn, the result ofwhich will be to present the side of the tumbler to the shackle- Varmsand pin 9, where the recesses are out of alinement therewith, and hencethe spring will normally hold a portion of the tumbler idr pin in therecessed portion,of the shacklellegs and pin 9 and prevent thewithdrawal of the shackle from the lock. Any number of these tumblers orlocking-pins may be turned and form part of the combination.

Whenuit is desired to unlock the lock, it is simply necessary to pushthe tumblers forming part of the combination, when the recesses thereinwill be brought into alinement with the shackle-legs and pin 9. A spring26, provided at the lower end of'the pin 9, will then force same upward,and the projection 11 on the upper end of the pin 9 will bear againstthe shoulder 13 of the shackle-arm 5 and f orce same upward. The pin 9will then serve to hold the tumblers forming part of the combination insuch position that the recesses therein will be in alinement with theshackle-arms and permit the easy withdrawal of the shackle until theshoulder-'14;A of the long arm 5 of the shackle abats against the lug orprojection 11 of the pin 9, which will prevent the entire withdrawal ofthe shackle, but permit it to turn (due to the recess 15in the arm 5) asufi-d cient distance tq release the articles locked.

` A metallic band-22e is adapted toLfit snugly around theframe',inc'losing the opening 2 and preventing the'withdrawal of the pin9.

,When it is desired to lock the device, itis simply necessary to forcethe shackle down- '.wardnntil the shoulderl en gages the lug orprojection 11 on the pinl9,' which will/force said pin downward andrelease ,the tumblers or locking-pins held thereby and permit same tospring into 'the recesses in the shackle-arms and pin 9, and hence lockthe shacklein place.

When it is desired to place a new tumbler or locking-pin in thecombination or to take out ofthe combination one already in, it issimply necessary to remove the band 27 and move the plates 18 of thatparticular tumbler or pin until the enlarged portion 21 is in alinementwith th@ tumbler and then give the tumblerI a halffrevolution and movethe plates 18 back, thus permitting the contracted portion oi--the slot20 to engage the dat parallel faces .23m-the tumbler, and hence securesame in Planegg., v ,v

*Ags many tumblers or pins as desired may be placed in the, combination,and it will be 'readily seen that with my improved lock the owner of thelock can readily change the combination of his lock as often as he likeswith practically littletrouble.

Various slight changes might be made in the general form and arrangementof the several parts described without departing from the spirit andscope of my invention, and hence I would have it .understood that I donot wish to limitmyself to the precise details set forth, but considermyself at liberty to make such slight changes and alterations asfairly'fall within the spirit and scope of my invention.

I claim as new, and desire to secure by Letters Patent, is
